Specification of Letters Paten-t.

Patented Nov. 3, 1914.

Application filed February 2*?, 1912. Serial No. 680,160.

To all whom t may concern Be it known that I, ELMER E. STONER, a citizenof the United States, residing at Stroudsburg, in the county of Monroeand State of Pennsylvania, haveV invented new and useful improvements inIceHarvesters, of which the following is a specification.

rihe general object of the invention is to minimize the time heretoforerequired'. to harvest ice. And to this end the invention consists in anice harvester which is adapted to move automatically in a requireddirection ony the ice field, and, while progressing between two pointson the said field, cut the ice in two directions.

Other objects will appear and be better understood from that embodimentof my inventin of which the following is a specification, referencebeing had to the accompanying drawings forming a part hereof, in which;

Figure 1 is a side elevation of one embodiment of my invention. Fig. 2is a plan of the same. Fig. 3 is a rear yend elevation. Fig. 4 is a viewsimilar to Fig. 2 with parts removed and broken away to disclose thedisposition of portions of the transmissionV mechanism. Fig. 5 is a viewpartly in side elevation and longitudinal section. Fig. 6 is a verticalcross section approximately on the line 66 of Fig. 5. Fig. 7 is a Viewsimilar to Fig. 6 but on the line 7-7 of Fig. 5. Fig. 8 is a detail planof the transmis sion mechanism. Fig. 9 is a view similar to Fig. 8 butshowing the parts in neutral position.

Fig. 11is a vertical cross section approximately on the line 11-11 of Fig. 10.Fig. 12 is a vertical cross section on the line 12-12 of Fig. S. Fig. 13is a fragmentary detail in side elevation of the controlling device forthe propeller. Fig. 1 4 is a fragmentary detail of one of the guides andits control. Fig.` 15 is a detail partly in section and elevation of thecontrol for the lateral propellers. Fig. 16 is a side elevation of amodified form of harvester. Fig. 17 is a plan of the same. Fig. 18 is anend elevation of the same. Fig. 19 is a detail of the lock. Fig. 2O is adetail of the latch. Fig. Qlfis a detail perspective of the keeper.

rl`he supporting or main frame, a, is suitably adapted, such as byproviding runners 5 5 of suitable material such as angle iron, fortravel on an ice field, and its base area `is such as to prevent themachine from toppling laterally while in use. To each of the runners5--5 there is secured a Vseries of spaced uprights 6-G, of `suitableconstruction and preferably of metal, which have their upperl endsconnected to the side portions 7-7 o f the platform 8 and serve assupports for the said platform.

The motor 9 which is herein shown to be of the; internal combustion type(although other types may be employed)` has its lbase 10 suitablysecured to thef'n'ieolial portion of the platform 8 and is arrangedsothat its crank shaft 11 ywill extendlongitudinallyof the frame a.

A suitable connection, such as by means of sprocketwheels 112 and 13secured respectivelyto the lcrank shaft 11 and stub shaft 14, andasprocket chain 15, is established between thesaid crank shaft 11 and"the stub `sha-ft 14 which has bearings in suitable hangers 16-16suitably connected to a suit'- ablefsupportor supports, such as theplat- .form 8. f

Suitable means such as a bevel gear wheel 17, yfixed to the stub shaft14, bevel gear wheels 18-#18 loose on ay counter-shaft 19 and meshingwith the bevel gear 17 and a clutch 20 sp-lined on the countenshaft 19,is employed for transmitting 'rotary movement in opposite directionsfromthe stub' means of a spur gear wheel 25 meshing with v the pinion 26, tothe counter-shaft 19 to which the pinionis suitably fixed.

By any suitable means such as sprocket wheels 27-27 fixed to theshortshaft 24, sprocket chains 28-28 and sprocket wheels 2.9-29, rotarymovementk is transmitted to the propeller shafts 30-30 journaled in drawheads 31-31 arranged in depending guides 32-32 suitably connected to thecor` ner portions of the frame a.

Suitable propeller wheels such as are in dicated by 33-33, are suitablyfixed to the shafts 30-30 and the spurs or teeth 34 of these wheels arenormally held in spaced relation toV the ice by suitable means such assprings 35-35 which are arranged in yokes 36-36 and which form supportsfor the draw heads as shown in detail in Fig. 13.

Cam shafts 37-37 have bearings in suitable supports such as arms 38-38connected to the ends 39e-39 of the platformS and in the upper portionsof the guides 32-32, and are operated by suitable means such as pinions40 meshing with rack bars 41-41 confined in guides 42-42 suitablyconnected to a convenient portion of the structure, such as the frame a.By preference the cam shafts are connected so as to be operatedsimultaneously. Any improved means may be employed for effecting thisstructure such as by providing the rack bars 41-41 with lateral'projections 43-1-3 to which are connected links 44 44 whichy connectwith rock arms 45%45 on a rock shaft 4G, journaled in suitable bearings46a and suitably connected such as by means of a link 4T, which connectsone of the rock arms 45,l with an operating lever 43 fulcrumed on 'therear end portion of the platform 8 and securable in any of its movedpositions by a latch and rack structurev indicated generally by 49, andas shown in Figs. 2 and 3. The cams 50-50 on the cam shafts 37-37contact with vertically extending offset portions 51-51 on the drawAheads 31-31. ...Thug when the parts are positioned as shown in Fig. 1,the draw heads 31 will be held .to the lower ends of the guides by thecams 50. In this position the springs 35 will be tensioned and thepropeller Wheels 33 adjusted so as to contact with the ice. 1f in orderto adjust the parts in these positions, it became necessary to movetheoperating lever forwardly or away from the operators seat 52, then whenthel operating lever is moved rearwardly or in the opposite directionthe portions of the cams asshown contacting with the draw heads in Fig.1, will move upwardly from the draw heads, thus enabling the springs 35to force the draw heads upwardly and until the propeller wheels areraised clear of the ice.

The clutch 2O is operated by suitable means such as a horizontallydisposed bell crank 53, one of the arms of which is adapted to oscillatean arm 54 pivotally connected as at 55, to the platform 8 and suitablyadapted at its lower end for shifting the clutch 20. A connecting rod 56has one end slidingly fitted in the bell crank 53 and has spacedheads-57-57 suitably secured thereto and between which and the bellcrank are When the operating lever 59 and the parts c connected theretoare moved so as to throw the clutch from the position shown in Fig. 9 tothat shown in Fig. 8, and with the motorin operation and the propellerwheels loweredas shown in Fig. 1, the machine will move in a straightline on the ice until such time as the propeller wheels are raised bythe instrumentalities previously described. In this connection it willbe observed that not only the progressive movement but also thedirection of such progressive movement of the machine, is controlled bythe clutch 20. j

The oppositely extending saw carrying frames Z) and c have their.opposite sides 62-62 swingingly mounted on or otherwise suitablyconnected to suitable supports such as the opposite end portions of thecountershaft 19. These saw frames which extend longitudinally of themain frame carrv at their forward end portions, shafts @3u-63 which haveone endportion projecting laterally beyond one side of the frame asshown inFig. 4. To theseprojecting end portions are suitably fixed thecircular saws 65-65- A suitable connection such as by meansof `pulleys(i5-66 fixed to the counter shaft 19, belts (S7-67 and pulleys 68-68, isestablished between the counter shaft 19 and the saw shafts 63.

Normally, the saw carrying frames ineline downwardly so as to hold thesaws in contact with the ice and by twisting one of the belts 67 asshown in Fig. 4, one of the saws is caused to rotate in a directionopposite to that of the other saw.

The frames are preferably swung independently of each other by suitablemeans such as rock shafts 69 and 70 which are suitably connected such asby crank arms 71-71 and links 72%72 to the sides 62-62 of the frames band c. A suitable connection such as by means of acrank arm 73 and alink 74, is established between the rock shaft and an operating lever 75fulcrumed on the-rear portion of the platform 8. A suitable connectionsuch as by means of a crank arm 76, and a link 77 is established betweenthe rock shaft 69 and an operating lever 78 fulcrumed on the rear endportion. of the platform S and adjacent to the operating lever 75. Theoperating levers and 7S have suitable latches 79 and 80 which coperatewith racks 8l an( S2 tov secure the levers in any of their' adjustedpositions.

When the `harvester is placed upon the ice and propelled by the wheels33-33 the l saws 65-,65 will out the ice aline parallel to the directionof movement of the "har-x vester. During the progression of the -harfEvester in making the ini-tial cuit it is not necessary to use .bothsaws, therefore, under normal conditions the parts are arranged `asshown in Fig. l when :the 'harvester is moving to the left in sai-'dligure The saws will 4now rotate in the direction of the arrows Y 83-83are suitably lined, extends longitndinally of the frame and isjournale'd in arms Saa- 84a which are loose upon a shaft 86f ljournaledin the hangers 85+'-85, depending from any suitable portion of theframe, suc'h as the platform 8, asshown in Figs. 3, 1, 5 and especiallyin Figs. 6 and 7 of the draw- I ings. The shaft 8-1 which ris bypreference' positioned below and 4parallel with 'the stub shaft 14, issuitably connected such as by a' sprocket 87,v a sprocket chain 88 andaf sprocket 89, with the'shaft 86', which latter is also suitablyconnected such as by the sprocket 90,the sprocket chain 91 and asprocket 92, with thestub 111.v

The draw` heads93-93in which the shaft 81 rotates, have their verticaldrawy rods 994 slidably litted in spaced guides' 95-95 formed withbrackets 96-96 suitably secured to and depending from any convenientportion `ol" the trame,'such as the yplatform 8. The heads 98-98 whichare the brackets -96-96, have levers 101e-101.

which bear on the upper ends of the draw.

rods 91.` The cranks 102-102 which arer Xed to the shafts 99-499, aresuitably adapted for loosely receiving the connecting rod 103, which hassuitably secured to it, heads 10a-104 which abut the cranks 102andioperate to move the same, whereby, to cause the lever 101-101 todepress the draw heads and lowerthe propeller wheels 83-83 into contactwith the ice when the foot lever 105 tulcrumed on the rear portion ofthe platform 3 and connected by a link 106 to the connecting rod 103, ispressed in one direction. Ifdesired, asuitable latchingfdevice (notshown) may be employed for locking the foot lever 105 any of litsadjusted positions, or the latch may be eliminatedas shown, so that whenypressure is removed yfrom the :said lever, the 'springs 97 will operateto restore it to its normal position and lift the lateral .propellers83.

y Either prior to or simultaneously with the lateral shifting of theharvester, the combined guides and stops 107-107 are permitted todescend into contact with the ice so as to .enter the cut and bear onthe edge of the ice, whereby,to indicate to the operator that themachine has been moved laterally sufficiently far, and to prevent anytendency of the machine to move laterally fin one direction, whilemaking the subsequent cut.` lThese guides may be of any suitableconstruction and are slidingly tted in brackets 10S-108 which dependfrom arms I109-109 which are braced by struts 1110-110, the said armsextending beyond the saws 65-65 for a distance equal to they standardlength of a cake of ice, or substantially so. Suitable elements such asspringsy 111-111 operate to force the guides 107 downwardly as shown inFig. 1 and the crank shafts 112-112, which are journaled in bearingsl113-113 and connected to the guides andk to a link 111, are adapted tolift the yguides when the link is operated byisuit able means such as arock arm 115, on .al` rock shaft 116 j ournaled in any suitable portionof the main frame 8 and-connected to a ioot lever 117, by any suitablemeans such as a connecting rod 118.

Th harvesterthus far described is adapta ed for selfmovcment on thefield of ice, for u cutting the'ice as it moves and for shiftinglaterally lfor a requiredl distance alter the making of a cut ofrequired length. le are now coming toa description of one embodiment ofsuitable mechanism, which, after the harvester has been4 shiftedlaterally, the parts adjusted and the clutch 20 thrown so as to causethe harvester to travel in a direction opposite to that in which ittraveled in making the lirst cut, to cut the ice `prei'- erably at rightangles to the initial and sub# lsequent cuts. By the provision of thismechanism the machine while making the subsequent cut,moves'intermittently or with such as the standard width or widths of oneor more cakes of ice, and in the pause between each step, the icebetween both cuts is divided into a cake or cakes of standard or anyother required size. This lateral cutting mechanism, so called becauseof its arrangement on one side of the machine, may consist of one saw oras shown in Figs. 1 and 2, the work may be 'greatly facilitated byemploying a number, preferably four, saws, indicated by 119 each ofwhich is spaced from the other for a distance oor.-

as the standard width of a cake of ice.. The shaft or arbor 120 uponwhich these saws are mounted, is journaled in the .sides crank shaft 11of the motor 9,. with pulleys 12S-128 on the opposite ends of the sawshaft 120. rlhe inner section of the frame d, or that made up of thesides 122-122, is rocked vertically by the cams 129-129 which operate onrollers 13G-130 carried by the sides 122-122, and which are fixed toIthe cam shaft 131 which is journaled in uprights 132-132 suitablyconnected to the platform S. This vertical rocking or swinging of theinner section of the frame also causes the outer section made up of thesides 121-121, to rock or swing vertically, whereby, to move the saws119 into and out of engagement with the ice. The outer section inaddition to being swung or rocked ver`A tically, is also swung or rockedlaterally by suitable means such as cranks` 133-133, which are formedintegral with or otherwise secured to the shaft 131 `and suitably connected such as by links 134-134, with pins 135-135 set into or otherwisesuitably secured to the side sections 121-121.

The throw of the cranks 133 is such as to project the saws suflicientlyfar to enter the ice at the initial cut, and to retract the saws throughthe ice to the subsequent cut and the cams are so constructed and timedas to allow the sawswhenover the initial cut, to drop into Contact withthe ice, and to raise the saws after they have been moved through theice to the subsequent cut.

Suitable means such as a'sprocket 136, a sprocket chain 137, and asprocket 137n on a sleeve 13S, are employed for connecting the cam shaft131 with a stub shaft 132.) upon which the sleeve 13S is loosely mountedand which is journaled in hangers 140-140 depending` from the platform8, or other suitable support. A clutch 141 is splined `on'the shaft 139and is operated by suitable means suoli as a cam, in the form of asprocket chain 142, trained over sprocket 143 fixed to the shaft 139 andover a` sprocket idler connected to the platform 3. rEhe lateralextensions 144 on the chain 142 are adapted to force the clutch from theposition shown in Fig. 8 to that shown in Fig. 9, and their number issuflicient to hold the clutch in the position shown in Fig. 9 until thesaws 119 havebeen projected, lowered, or moved through the ice to thesubsequent cut and again raised, at .which time the last of the lateralextensions 144 will have cleared the clutch, as shown in Fig. 8, and thelatter will be restored to its original position and unclutched bysuitable means such as a spring-pressed operating arm 145, suitablyconnected to the clutch and pivotally connected to the platform S, asshown in Fig. 10.

' Whenthe machine is in motion and cutting with one of the saws 65, oneof the gear wheels 18-18, will, depending upon the direction in whichthe machine is moving, be connected with-the clutch 20. As shown inyFig. 8, -when the clutch is lmoved into engagement with one of the gearwheels, that arm ofthe bell crank lever 53 which is connected to theclutch through the operating rod 54, will extend obliouelv to theclutch, regardless as towhich of the wheels 18-18 with which the clutchengages. Now the angular-shaped end portion 146 on the said arm of thebell crank. lies in the path of movement, depending on the wheel with'which the clutch engages, of one of a pair of pins 147-147 dependingfrom a lateral extension 148 carried by the operating member 145, whenthe said operating member together with the clutch 141, is moved intoengagement with the sleeve 138 by means of the cam chain 142. Now if theparts be positioned as lshown in Fig. 8, and the operating member 145moved toward the bell crank, the outer pin 147 on the extension 14S willengage with one sideof the angularshaped extension 146 and rock the bellcrank lever together with the clutch 20, to the posi tion shown iny Fig.9. This will have the eii'ect of stopping the progressive movement ofthe machine during the time that the saws rv119 are cutting the ice.After the ice has been cut by the saws 119 and the projections 144 movedout of contact with the clutch 141, the spring 149 coperates with thespring 150 for the operating lever 145 to withdraw the said operatinglever andthe extension148.

Referring now to Fig. 8, the springs 58-58 are not perceptiblycompressed when the connecting rod 56 is moved so as to operate theclutch 20. In as unich as the lever which operates the rod 56, is lockedby its latch when the clutch is clutched with either of the wheels18-18, the said rod 56 will not move when the bell crank is operated byeither of the pins 147. But during such operation of' the bell crank byVeither of said pins, for instance, by the pin before stated, the bellcrank will operate to compress one of the springs 58 when the clutch ismoved to neutral position, as shown yin Fig. 9, so that upon thewithdrawal of the extension 148, as previously described, the compressedspring 58 will ope-:rate to yrestore the bell crank and the clutch totheir original positions, as shown in Fig. 8. This will enable the'machine to continue its progressive movement until suchltime as theclutch 141 and the parts coni-,iected thereto, are operated to operatethe saws 119 andl the bell crank lever 53,. The cam chain 142 is soconstructed as to operate the clutch 141 only at the time the machinehas progressed for a distance equal in length to the com'- bined widthsof four cakes, or substantially so. j

A suitable connection such as by meansof a'sprocket wheel 151, sprocketchain 152, and a sprocket wheel 153 fixed to a sleeve 154, isestablished between the shaft 139 and a stub shaft 155 arrangedsubstantially coextensive with the stub shaft 14, and journaled inhangers 156-156 depending'v from the platform 8, or other suitablesupport. A clutch 157 is splined on the shaft 155 and operativelyconnected by suitable means such as a connecting rod 158, to anoperating lever 159 fulcrumed on the rear portion of the platform 8 an-dadjustably secured by a latch 160'and a rack 161. A suitable connectionsuch as by means of a'sprocket wheel 162, a sprocket chain 163, and asprocket` wheel 164, is established between the crank shaft 11 of themotor and the shaft 155.

From the foregoing the .operation of the invention will be Vlargelyunderstood and when it is remembered that when, for instance, theforward saw in Fig. 1, is arranged to cut while the machine is moving inthe direction to the right in said figure and the propeller wheelsarranged so asto con-- tact with the ice and the motor started, themachine will trai/*el continuously for any required distance in orderto.` make the initial cut.

Whenfa cut of suiiicient length has been made, the machine is shiftedlaterally by the mechanism before described, and until the guides Lenterthe saidy cut. This done,

both propelling mechanisms are rendered inactive by their respectivelevers and the mechanism for the side saws is thrown into operation.This will have the effect of causing the side saws to cut the ice forthe required distance after which the side saw mechanism is renderedinactive by unclutching the same and the .clutch 2Ov` operated so as tocause the machine to go in a direction opposite to that in which isproceeded while making the initial cut. kThe sawA on the right in Fig. 1is then lowered, vand as the machine progresses the ice between the cutslnade by the side saws, will be severed. The

machine is now permitted to advance'y with automatically stop and theside saws go into operation. After which the machine will operateautomatically to make the subsequent and lateral cuts until it arrivesopposite the stationary of the initial-cut', when it is shiftedlaterally and started in the opposite direction, as before described. t

In using the modified form` of harvester shown in Figs. 16 to 18inclusive,L l arrange ay track of any desired length, onthe ice fieldand secure the rails 165-.-165 thereof by ysuitable, means ksuoli asspikes 166--166 The supporting frame 167 is providedwith suitable flangewheels 168,-,-168 whichfare adapted to travel` on the rails 165-165 fand suitable keepers 169 are arranged on vone of the said rails 165and'spaced from` each otherfor a distance,corresponding toy the l?, j

standard width of a cake kof ice, orforany yother suitable distance.l'.lhe springpressed latch 170 which is suitably connected to the fsupporting frame 167as`shown in Fig?. 20,

is positionedv so as to be cammed outwardly by one ofthe cam ends171 ofthe keepers as the frame advances onthe track anduntil the latch alineswith thek opening of the keeper, whereupon its spring 17 2 will force iit inwardly and lockthe frameto the track, as shown in Figs. 416 to 18inclusive.` `The 19, is adapted when moved in one `direction latchoperating rod 173 whichy is pivotally l connectedtothe frame 167 asshown in Fig.

to force the engaging'end of the latch from the keeper 169, as,shownbydotted lines in Fig. 20. This is done when it is desired tounlock the frame 167 in order that it may be advanced to the succeedingkeeper.

The turn table 174 which is mounted upon a spindle 175 suitably securedto the frame 167,'supports the internal .combustion motor 17 6 whosecrank shaft 177-is extended at one end so as to project considerablybeyond the turn table and frame, and is journaled in a boxing 178 `onthe uppervends of up? rights 179wwhich connect lto a supplemental frame180, which is connected to and eX` tends laterally from they turn table174.

' The sides 181-.-181 of the inner section of the saw frame c, areconnected bytie rods 182-182 andl are turnably mounted on the vShaft177,. The sides 18S- 1.83 of the outer section of thesaw frame, pivot ononeof the tie rods 182 and in their lower ends is journaled the sawshaft 184, one end ofy which rextends beyond oneofl the sides 183 y andhas secured thereto lthe. circular sawl 185. The belt 186 is trainedover apulley 187 fiXed to the engine shaft 177 between 70 traversed thedistance before stated, 1t will the shafts 181 and over the pulleys of a13o ielt tightener 188, and over a pulley 189 on engage the strut fromthe cross piece.

,lat-ch 1s then moved from engagement with a keeper 193.

the saw shaft 184.

The saw frame c 1s raised and lowered by pressing 'on an operatinghandle 190 su1tably secured to the inner section of the saw frame. Bythus operating the said saw frame the saw 185 is moved into'and out ofcontact with the ice. n

@ne mode of using the device thus described, consists in arranging theparts as shown in Fig. 16 and permitting the saw to descend into Contactwith the ice, which is done by operating. a lever 197 connected by meansof a link 196, to a strut 195 which in terlocks with a cross piece 198,so as to 'listhe keeper 169 and the harvester pushed along the track andfor the entire length of the track. During this operation the saw ismanipulated by the handle 191 so as to cut the ice.l This will make aninitial longitudinal cut with respect to the track. ,Thev

track is then shifted laterally from the initial cut for a distancecorresponding to the lengthof cake'desired, whereupon the harvester iscaused to move as before and a subsequent cut parallel to the initialcut, is made by the saw.
